The utility model has the advantages of simple operation, quick and accurate counterparts, and the welding deformation is reduced due to the jack jacking to the welding.
【技术实现步骤摘要】
本技术涉及一种机械,用于管道安装,具体而言是一种对焊法兰与管道连接内对口器。
技术介绍
目前,在管道与法兰对焊施工过程中,还在使用人工调整对口的方法,效率很低,人为因素影响大,对于大直径法兰焊接时存在偏差错口,同心度难以准确控制,目前的各式管道对口装置中,已管道对口为主,外对口器设备简单,但不适用法兰与管道对焊,内对口器设备复杂,操作烦琐。现提供一种操作简单,高效,无错边,同心度准确的法兰与管道对焊连接对口器,以适应各型号法兰与管道对口施工的需要。
技术实现思路
本技术要解决的技术问题是提供一种法兰与管道对焊内对口器,保证不同直径法兰与管道连接时的同心度,使对口迅速、准确,直至焊接完成,减少焊接变形。本技术由上支圈、下支圈、转轴、上支板、下支板、上筋板、下筋板、定位垫片、千斤顶和顶紧螺杆组成,上支圈、下支圈均为半圆形圈,上支圈、下支圈均焊接有定位垫片,上支圈与下支圈之间通过转轴铰接,上支圈的内侧焊接上筋板和上支板,下支圈的内侧焊接下筋板和下支板,上支板和下支板之间通过顶紧螺杆连接,千斤顶设置在上支板和下支板之间。本技术工作时由预紧螺栓先将法兰和管道初步定位,再用千斤顶顶紧后进行焊接操作,达到焊接目的。本技术操作简单,对口迅速、准确,由于千斤顶顶紧至焊接完成,减少了焊接变形,极大的方便了施工。安装企业使用,适用多管径,机械费低,可以提高工效,综合效益十分显著。附图说明图1是本技术的结构图。图2是本技术的左视图。图3是本技术俯视图。图4是图1中I部的局部放大图。图中,1、下支圈,2、转轴,3、上支圈,4、定位垫片,5、上筋板,6、上支板,7、千斤顶,8、预紧螺杆 ...
